RedPanda I'm not sure (because I am not using NFC ) but if you have google services somehow, maybe you can enable nfc on curve. someone said above that if you change region to Iceland, Curve lets you activate nfc. https://appgallery.cloud.huawei.com/appdl/C102372409
There is also another app called "Lydia" (now Sumeria.eu). It has Nfc Function (at least for Huawei phones) but supports a limited number of countries.
🇫🇷 Metropolitan France and DROM-COM (numbers starting with +33 +262, +596, +590 and +594)
🇲🇨 Monaco (+377)

You might be able to use that. If there isn't any option to activate payment, maybe it needs google services. someone has said to me that it works as NFC payment app on GMS devices too.
Those are the two that have mobile payment on their own (at least for Huawei phones)
You could try them with and without google services (maybe with microg) and keep us posted!
